A series of cold fronts continues to clip southern Australia, bringing an increase in wet weather every day or two near the coast.

The pattern continues for much of this week - however there will be an anomaly.

Monday morning's weather map

The cold front clipping the west today has an upper atmosphere cold pool that will dislodge itself from the fast moving westerly flow to the south.

What this means is: we have a ball of energy that can do it's own thing and take its own path.

This ball of energy is connecting with a weak feed of tropical moisture from the Indian Ocean - and that connection helps increase the rain.

This rain system is set to track across Western Australia, South Australia then western NSW on Monday and Tuesday, clearing early on Wednesday.

If you're on the Eyre Peninsula or Flinders part of SA, then you've hit the jackpot with this one - with 15 to 30 mm coming your way.

Potential rainfall over the next few days
